CARLETON ELLIS, 0F WHITE PLAINS, NEW YORK, ASSIGNOB, T0 CHADELOID CHEMICAL COMPANY, OF .NEW YORK, N. Y.,. A CORPORATION OF WEST VIRGINIA.

To all whom it may concern;

Be it known that I, CARLETON ELLIS, a citizen of the United States, and resident of White Plains, in the county of Westchester and State of New York, have made a certain new and useful Invention Relating to Paint or Varnish Removers, of which the following is a specification.

Thisinvention relates to paint or varnish removers and relates especially to removers comprising amino solvents for use on painted surfaces.

Many of the amino solvents, that is, hydrocarbon bodies containing the amino or NH group are valuable solvents for-paint and varnish films and especially desirable in removing ordinary'paint. Such ofthese bodies, which, of course, include the amino bodies, as have the proper fluid condition under ordinary temperatures, may be used for this purpose, both in the aromatic and 3 the aliphaic series of hydrocarbons. Illustrative examples of such aromatic amino solvents are anilin, toluidin and xylidin, the lower members being more active solvents in '.most .cases. An aliphatic amino solvent of this character is butylamin. These amino solvents, preferably of the anilin order, may

- be used in removers in connection with suitbe used, that is, solvent material-of a generally alcoholic character or actionjin removers, including grain, wood or denatured alcohol or ketonio solvents, such as acetone, methyl ethyl ketone, acetone oil, ethyl butyl ketone, aldehydes and so forth, as well as other hydrocarbon solvents. Although not necessary in all cases, suitable stifi'ening material, such as wood flour, starch, whiting, infusorial earth and soa y or waxy bodies, such as ceresin or para 11 wax, may be used to increase the consistency of the remover; andto decrease evaporation by the film-forming properties of the waxy or soapy bodies. 0 preferably thoroughly incorporated by agi- Specification of Letters Patent.

All these ingredients are Patented July 4, 1916.

Application filed February 25, 1907. Serial No. 359,264.

tation under the desired moderate heat, the waxy or soapy bodies being preferably first dissolved in the more energetic wax solvents, although this is not always necessary.

An illustrative remover of this character, especially suitable for use on paint coatings, may comprise anilin 20 parts, benzol 10 parts, acetone 1O parts, ceresin wax 1 part, Wood flour 3 parts, starch 2 parts.

Another illustrative remover may comprise toluidin 5 parts, anilin 10 parts and ceresin wax 1 part.

Still another illustrative remover, more especially suitable for tank work, may comprise anilin' 100 parts, lightest grade of kerosene or heavy benzin 100 parts, commercial xylol'25 parts and'ceresin wax 1 part, althou h it is, of course, understood that the sti ening material is not necessary in all cases.

This invention has beendescribed in connection with a number of illustrative ingredients, formulas, proportions and processes, to the details of which disclosure the invention is not, of course, to be limited.

What is claimed is 1. The paint or varnish remover comprising approximately anilin 20 parts, benzol 10 parts, acetone 10 parts, ceresin wax 1 part, wood flour 3 parts andstarch 2 parts.

2. The paint or varnish remover comprising approximately anilin 20 parts, benzol 10 parts, acetone 10 parts and stiffening material, including wax.

3. The paint or varnish remover comprising approximately'anilin 20 parts, benzol 10 parts, loosening finish solvent material 10 parts, and stiffening material, including a waxy body. 4. The paint or varnish remover comprising approximatelyamino finish solvent material of the anilin order 20 parts, aromatic solvent material 10 parts, loosening finish solvent material '10 parts and stiiiening material.

5. The paint or varnish remover comprising amino solvent material of the anilin or der, miscible penetrating and loosening finish solvent'material, and st'ifi'ening material.

6. The paint or varnish remover comprising organic amino finish solvent material,

other finish solvent material miscible there- I with, and stiffening material. 7. The paint or varnish remover comprising amino solvent material, loosening finish 10. The paint or varnish remover comprising approximately anilin 20 parts, a benzol solvent 10 parts, and loosening finish solvent material 10 parts.

11. The paint or varnish remover comprising approximately amino solvents of the anilin order 20 parts, benzol 10 parts, and loosening solvent material 10 parts.

12. The paint or varnish remover com prising aromatic amino solvents, other paint or varnish solvents miscible therewith and incorporated evaporation retarding stiffening material. 1

13. The paint or varnish remover comprising solvent liquid containing the amino group, finish solvent material miscible therewith, and stiffening material.

I 14. The paint or varnish remover comprising-amino solvent material, incorporated miscible volatile organic finish solvent material and waxy stiffening material.

15. The paint or varnish remover com prising amino solvent material, incorporated miscible volatile organic finish solvent material including ketonic loosening material ing material.

and evaporation retarding stiffening material.

16. The paint or varnish remover comprising a solvent liquid containing the amino group and volatile organic finish solvent material miscible therewith.

17. The paint or varnish remover comprising a solvent liquid containing the amino group, incorporated organic finish solvent material miscible therewith and evaporation retarding stifiening material.

18. The paint or varnish remover com' prising composite, organic finish softening material including amino solvent material and incorporated waxy stiffening material.

19. The paint or varnish remover consisting in large part of composite volatile finish softening material including amino solvent material and aromatic finish solvent material and waxy stiffening material.

20. The paint or varnlsh remover consisting in large part of composite volatile finish supporting materialv including substantially neutral amino finish solvent material and aromatic finish solvent materlal and stlfien- 21. The palnt or varnish remover comprising approximat'ely anilin 20 parts, aromatic finish solvent material including benzol 10 parts and stifiening material.
